Max, if you're serious about getting carbons then get rid of the overdraw. You don't need it with carbons. They are light enough to give you all the speed you'll want. I used to shoot for XI and can say if you start shooting short carbon arrows at 26.5" and 80# in the spine deflection (not spline) of .400" you're going to need a bow pretty soon because your limbs are not built for that. In fact most newer bows are not either. Best bet is to put your rest on the riser and shoot a full length arrow such as Beaman or Easton 300's.
